Allow Dojo require() to fail - error-handling

I have a require statement that loads in a layer that I build with Dojo. I want to be able to test my code without having to build my Dojo source every time. However, if I don't build and the require statement is called, it fails with a 404 error.
Is there any way to catch this 404 error and allow it to fail?

Any module in an application can be converted into a “layer” module, which consists of the original module + additional dependencies built into the same file. Using layers allows applications to reduce the number of HTTP requests by combining all JavaScript into a single file. Creating a new layer file just for the production version of your application is not the correct way to create a build. Instead, build into a module that you’re already loading in development. Then, your require calls never change between development and production; the only difference is that your layered modules contain their dependencies.

Definition mx.binding.utils.BindingUtils could not be found similar couple of imports not loading

I got chance to migrate Flex application to Apache Royale, able to run helloworld applications. started migrating Application, getting couple of exceptions. bellow is the one.
we are using the
AdobeSpelling.swc
AlivePDF.swc
Cairngorm.swc
flexmdi.swc
FlexUnit.swc
spcairngorm.swc
these '.swc' libraries.
how can i import these or is any similar libraries in royale compatible files.
i found asconfig.json file - external-library-path - but i am compiling my application with maven pom.xml.
Please help me, basic migrations
Error Log:
Warning: Definition com.model.ModelLocator could not be found.
import com.model.ModelLocator;
Warning: Definition com.util.customComponents.CustomMenuBarEvent could
not be found.
import com.util.customComponents.CustomMenuBarEvent;
There is two path which you can go in case of migrating.
Emulation Components. However there is a chance that some of
the components wasn't added to emulation so you may get exceptions
and this would be the place where you can add them and make pull
requests to Royale. Those components allows you in best case
successfully build your application without changing drastically UI
part, but you may won't see anything on the screen or it may be
messed, cause there wasn't volunteer who could work on displaying
better them.
Another path is to distinguish your pure ActionScript code (no
dependency to Flash) from UI part - pure AS3 code should ported
without any problem - and rewrite UI from scratch using Basic module
or Jewel
All libraries which you have mention have strong dependencies to Flash, so my recommendation is to find JS replacement for them and use it in your porting. There is also PureMVC which is working pretty good with Royale - it's has been tested in several applications already.

TFS Build ignores configured Code Analysis ruleset

I have a solution that is using an hybrid .csproj and project.json combination (for nuget management purposes). So basically the "project.json" file is working as a "packages.config" file with a floating version capability.
This solution is using a custom RuleSet that is being distributed via Package, and is imported automatically. On the dev machine, works without a problem.
At the build machine (that is, inside the machine itself, working as an user) the solution also compiles without a problem.
However, when a vNext build (is this the name for the new build system?) is queued, it ignores completely the custom ruleset and just uses the StyleCop one (that is also included), which gives a bunch of warnings. Said warnings should not appear as the Custom RuleSet basically suppresses those warnings (ie: Warning SA1404: Code analysis suppression must have justification,
Warning SA1124: Do not use regions, etc)
As far as I have checked, there is no setting to specify the ruleset, and this works with XAML Builds. What is different in this new build system that is causing this? Is there a way to force/specify the Code Analysis Rule Set from the definition?
Thanks in advance for any help or advice on the matter.
Update/Edit
After debugging back and forth with the wonderful help of jessehouwing I must include the following detail on my initial report (that I ignored as I did not know that it was influential):
I am using SonarQube Analysis on my build definition.
I initially did not mention it as I did not know that it replaces the Code Analysis at Build Time (and not only when it "analyzes", as I thought).
If you are using the SonarQube tasks
The SonarQube tasks generate a new Code Analysis Ruleset file on the fly and will overwrite the one configured for the projects. These rulesets will be used regardless of what you've previously specified.
There is a trick to the naming of the rulesets through which you can include your own overrides.
More information on the structure can be found in the blog post from the SonarQube/Visual Studio team. Basically when you Bind your solution to SonarQube it will generate 2 ruleset files. One which will be overwritten during build, the other containing your customizations.
There is a toolkit/SDK to generate a SonarQube plugin for custom analyzers which allow you to import your rules into SonarQube, so it will know what rules to activate for your project(s).
If you're not using SonarQube
Yes you can specify the ruleset you want to use and force Code Analysis to run. It requires a couple of MsBuild arguments:
/p:RunCodeAnalysis=true /p:CodeAnalysisRuleset="PathToRuleset"
Or you can use my MsBuild helper extension to configure these settings with the help of a UI template:

Load package dynamically

Is it possible to load a specific package during runtime?
I want to have a kind of plugins where each one has the same functions than the others but with different behaviour, and depending on the configuration file, load one or other.
No, Go doesn't support dynamically loaded libraries.
Your best bet is to start the plugin as its own executable and communicate with it through sockets or via stdin/stdout.
2017 update
This answer is no longer true, Go now supports plugins (for Linux and MacOS only as of June 2021)
There is support for this now as of go 1.8
https://golang.org/pkg/plugin/
You might consider executing the ‘plugin’ packages at runtime, by writing out a new program (say, to a temp directory) and executing via exec.Command, something along the lines of exec.Command("go", "run", files…).Run()
You’ll see some similar code here.
Just do these,create a codegen that reads the configuration, generates a basic go file with the packages loaded in order and then execute that, compile languages won't nor provide dynamic loading, even dart suffers in a way,simple just read your configuration file then create a temporary file with the necessary codes to load up and communicate with sockets or http
I think what you are looking for is the special function init
if you add a
func init() {
}
inside a package it will run it the first time the package is imported.
This happens only in the same binary. As other have already said go does not support dynamically loaded libraries.

Build server fails to load custom code analysis ruleset

We are using Code Analysis on our projects. As part of this we have Code Analysis enabled on the build server allowing for continious checks.
Now we are receiving this error:
CA0063 : * Failed to load rule set file '[name].ruleset' or one of its
dependent rule set files.
[name] being a ruleset on our internal network, available for everyone.
Code Analysis runs perfectly fine on each local machine, but not on the build server. How can we fix this issue?
Notes:
We use a custom made ruleset
We are not using any custom rules (yet)
I was having this issue as well. How I solved it was to add my custom ruleset into version control (Git) as a new directory within my project files. We are using Jenkins for our CI, so in my Jenkins.build I then made sure to specify the absolute file path to my ruleset on the Jenkins server, which you can get by looking at your Workspace on Jenkins. For example the path may look like :
e:\Jenkins\workspace\SampleProj-Dev\Rulesets\CustomRules.ruleset
In Jenkins.build file, I added an argument to the msbuild.exe program execution with:
<arg line="/p:RunCodeAnalysis=true;CodeAnalysisRuleSet=e:\Jenkins\workspace\SampleProject-Dev\Rulesets\CustomRules.ruleset"/>
Before I had tried using a relative path but with a build containing many sub-projects, Jenkins tried to append the path onto a changing path. This path was based on the currently building sub-project, resulting in the same error you received.
I stumbled onto a fix for this tonight for a project that has been suffering from it for ages. I created a new configuration CHECKED and the problem disappeared. Then by:
Deleting the existing configurations from Configuration Manger;
Exiting and saving (this step might not be necessary); and finally
Recreating the dropped configurations from the newly created one, CHECKED
the problem has now disappeared completely in all configurations.
This was all in Visual Studio 2013.

pydev: undefined variable error when importing compiled modules

I want to switch my python-IDE from idle to pydev (eclipse). I am using a couple of modules which I have as compiled bytecode (*.pyc) only. In idle that was never a problem and it even offers code completion for those compiled modules. But pydev gives me a lot of "undefined variable" errors - however the code is interpreted correctly.
Is there a way pydev can handle bytecode modules the way idle does? Perhaps without decompiling the files?
Try adding the modules as forced builtins.
To do that, go into Settings → PyDev → Interpreter - (Python/Jython/IronPython as approriate), select the interpeter you're using, and add it to the list on the Forced Builtins tab (look here for more details).
(Note that you may or may not have to add multiple entries for subpackages and modules; for example to get Fabric working properly one needs to add both fabric and fabric.api)
That makes PyDev load those modules into an interpreter to get code-completion and error checking data, rather than just analysing source code.
I've not tried it for .pyc files, but it works for other things like importing something that's generated dynamically by a script's __init__.py or something (ie fabric) so it might work for you.
(see also this FAQ and that one on the PyDev site)
